This invention. relates to multiple intake valves, and particularly to a turning plug valve adapted to have-1ts intakes connecte with difierent sources of supply.

5 An object is to provide a valve of th 1s character which can be set to draw liquid from both intakes, or to close off both 1ntakes, or to connect the discharge with only one of the intakes, the structure being such that the proportion'of liquid or fluid passing 3 through the valve from the'two intakes can be varied. v 1 A further object resides in so constructm the parts that the turning plug can be a 16 j'usted to take up looseness, due'to wear or other causes, and thus maintain the valve always in most efllcient condition.

A further object resides in so constructing the turning plug and the passage within the 20 valve that hquid passing therethrough W111 not have a clrcular or swirling travel, and consequently spray at the discharge Wlll be avoided.

' With the above and other objects in view, 95 which will be apparent to those skilled in the art, our invention includes certain novel features of construction and combinations of parts which will now be set forth.

In the drawing: Figure '1 is a vertical sectional view through a valve constructed. in accordance with our invention.

Fig. 2 is a view in elevation, taken from the intake end of the valve.

Fig. 3 is a fragmentary sectional view on the hue 3-3 of ig. 1. 1 Fig. 4 is a sectional view taken verticall througha modified form of valve s ructure. In the main embodiment, the shell is sup- 40 'orted in vertical relation by a neck which has the horizontally extending spaced intake passages 3 and 4. The shel otherwise hollowed out and the opening thereofis formed on a long, gradual taper, this opening terminating at its lower smaller end in a discharge mouth .5. The intake. passages ,3 and 4 open into the passage of-the shell 1 and arehorizontally spaced, the re- -ma.iningends of these passages being threaded or otherwise adapted for connection. to

sources of liquid or fluid supply.

The turning plug 6 is tapered to corre-' spend with the tapering of the shell. passage 7 and is made of a diameter to fit and turn 1 is cored or,

within that portion of passage 7 into which intake passages 3 and 4 open. .This plu 6 has a. central passage 8 opening through that end disposed adjacent the discharge mouth sages 3 and4. The'wa of discharge passage 8 in the plug 6 is flattened-asat 10,1and this flattened side is disposed opposite the port 9, so that liquid or fluid passin through the port will strike against the Eat wall and SWlIllIlg or rotating currents will be broken The plug 6 has an operatin stem 11 extending axially from the hea end thereof, and an operating handle'12 is carried by the end of this ste v The upper end of passage 7 is internally screw-threaded, and' an adjusting nut .13, hav1ng a n o ning to recelve stem IE1, is turned into t is threaded end of the passage to bear-against the head of plug 6 and hold the lu in proper fitting within the passage -7 o s ell 1. This admstingnut can be turned lnto place and adjusted by the use of a spanner wrench or other suitable tool. A cap 14:, having an opening through which stem 11 passes, is turned into the threaded end of passage 7 to form a bearing for stem 11, and to close the open top of the shell 1.

In the use of our improved valve, the intake passages 3 and 4 will be connected with separate liquid ,or fluid su plies, and the valve is preferably supports 1n the position shown in the drawings, with the dlseharge mouth 5 downwardly. When it is desired to draw off liquidfrom one. of the 'intake passages, the plug 6 is turned to bring port Continued turning of the plug will dispose the port 9 to establish communication with both of the intake passages, andby adjusting the position of the valve plug 6, the de-' gree of openin from the two passages can be proportione to correspondingly proportion the liquid from the two sources of sup-' ply. Liquid passing through port- 9 will" flow' from discharge-mouth 5, and as the stream of liquid strikes the flattened wall or side 10 in the discharge passage 8 of plug1 6, swirling or circular movement is stoppe and cdnsequenfly there will be no spray or splashing at the discharge mouth of the valve,"

In, the modified construction, referring to Fig: 4, the shell 1 is constructed in the same manner as hereinbefore described, and any number of intake passages can be provided with their inner ends in communication with the passage of the shell. The turning plug 15, turning within shell 1, is provided with a tapered passage, this passage being internally screw-threaded at its u per end. A port 16 is provided through p ug 15 in line with the intake passages of the shell, and a second turning plug 17 is mounted to turnv within the plug 15, this second plug having 'a port 18 which lines up with port 16 and the intake passages of the shell. An adjusting nut 19 is turned into the threaded end of plug 15 to properly hold plug 17 in its working osition, the turning stem 20 of plug17 being extended through this nut. A

hollow turning stem 21, revolubly receiving stem 20 is provided with a threaded flangev to be turned into the threaded end of plug 15 to jam against nut'19, and a locking nut 22 is provided to retain this stem 21 in place,

This modified form of the valve structure provides a double seal between the intake aiiddischarge, and with theuse of this structure, it will be possible to provide a plurality of ports 16 through plug 15 and secure a wider range of opening and closing a justments by manipulating the two turning lugs.

While in the foregoing we have shown and 7 described only certain specific. embodiments, it will be apfigeciated that changes and variations can made in the form and arrangement of the parts, without departing from the spirit an scope of-our invention.

We claim: 1. In a valve, a shell provided with a discharge passage and having an intake passage opening laterally thereinto, a' turning plug mounted in the shell in line with the intake passage, and provided with a substantially circular bore opening for discharge at one end, said turning plug having ly through said turning plug in line withv the intake passage, and at a point diametrically opposite the flattened wall of the bore. 3. A valve comprising a shell having a valve-receiving opening therein, spaced and separated intake passages leading into said valve opening, a turning plug valve mounted in the opening in line with the intake passages, said turning plug valve having a sub stantially circular bore therein opening to discharge at one end and flattened on oneside, and a lateral portthrough the wall of .the turning plug valve diametrically oppod sitethe flattened wall elongated laterally to communicate with the two assages when the plug is turned to an open position.

In .testimonywhereof we aifix our slgnatures.
